At the end of the 19th century, the first artificial ice rink was opened in England. The technology for creating artificial ice has undergone many changes. At first, it was a rather complicated and time-consuming process - workers leveled and filled ice with shovels by hand. In the 40s, the first ice-making machine, the ice harvester, was invented. We owe its development to the Canadian Frank Zamboni. Today, several such machines are already operating on modern artificial skating rinks, literally in a matter of minutes the ice is already perfectly flat. Recently, the developers have presented a novelty - a synthetic ice rink. On "synthetics" you can calmly cut on skates with metal blades. Synthetic analogs are cheaper than artificial skating rinks and are massively used in America and European countries.
